This report describes the evaluation of a scheme using new technology to give priority to buses at junctions along a congested bus route in Eastleigh, Hampshire, as part of the ENTRANCE project. In Eastleigh, the aim was to reduce delays to buses at traffic signals and to improve the reliability of services, improving the attractiveness of public transport relative to the car. Benefits for energy consumption and the environment were expected. Buses were given priority at three junctions controlled by the SCOOT Urban Traffic Control System, and at one isolated junction. Loop detectors were installed in the road approaching the junctions and buses were equipped with electronic 'tags' to communicate with the loops. When buses are detected by the loops, they are given priority by extending an existing green phase in the traffic signals or by calling up a new green phase. The scheme met the objectives of reducing delay, emissions and improving fuel consumption of buses using the junctions. By optimising the priority settings, net benefits in fuel consumption, emissions and costs could be obtained for other traffic. The application would be suitable for wider implementation. Further research is proposed to develop bus priority strategies for congested conditions. (A)
